Description
The Enhanced Mini USB port is an inovation that will change
the way external plugs are used together with cell phones. This
port provides users a single interface to connect audio hands-free
kits, audio stereo headsets, battery charger, or USB data cables.
Pericom has develped a unique, single IC, that enables the cell
phone designer to provide such features. Pericom’s PI3USBA03
offers two channels for high speed USB 2.0 signals (480Mbps),
and the other channels are used to pass the stereo and mono audio
signals through. Each input/output has high integrated ESD, up
to 12kV HBM protection, per JESD22 specication. This single
chip solution integrates three ICs into a single easy to use solution.
PI3USBA03 also offers PCB board savings with a total package
size of 1.3mm x 2.8mm.
